To @ZZ whom it may concern:

Se it known that I, WILSON F. HUTcHIsoN, a citizen ofthe United States,residing at Sherman,'in the cpunty of Graysouand State of Texas, haveinvented a new and useful Flue- Beader, of which the following is aspecification.

This invention relates to means for beading, swaging, or upsetting theends of boiler flues or tubes after the latter have been placed inposition in the boiler-heads, so as to secure a steametight joint, aneat iinish, and a substantial connection.

The' object of `the invention is tol provide a 'tool which can berotated and Will successively and gradually turn the projecting end otthe tube or iiue without unnecessarily straining or disturbing thefibers of the tube to Such an extent as to create fracture or weaken thebeaded end.

A further purpose of the invention is the construction of a tool whichWhile being rota ted can be forcibly and positively advanced Setting ofthe flue or tube without requiring any special effort on the part of theWork man taller than that necessary to rotate the tool, so as to attainthe object in view.

` With these and other objects in View, which will appear to one skilledinthe art `as the nature ofthe invention is uliderstood, the improvementconsists of the novel features and combinations of t-he parts, whichhereinafter will be vmore particularly set forth, illustrated, andfinally embodied in the subjoined claims. The improvement is susceptibleof various changes in the form proportion, and the minor details ofconstruction without departin from the principle or sacriicing any oftheadvantages thereof, andto'a full disclosure of the invention anadaptation thereof is shown in the accompanying drawings, in Which--Figure 1 is a perspective view of a tool conbearings t being interposedbetween the shoulder 2 and head 3 to relieve the friction between -theseparts when they are relatively turned. Theouter end of the ,head' isdepressed, formiug two faces 5 and which stand at an angle relative toeach other. A bead 7 is formed on the face 5 and a corresponding beadSis provided onthe face 6, and these beads 7 and 8 form annular tracksfor calli-ing and swaging rollers to travel upon when the tool is inoperation.

The sWaging-rollers 9 and the calking-rollvers 10 are similarly formedand .are alternately arranged, the sWaging-rollers 9 being placed totravel upon the face 5 and. track 7 and the calking-rollers 10 tooperate upon the face 6 and track 8. Both sets of rollers haveperipheral grooves intermediate of their ends which correspond toltheforrn of the track against whichthe rollers bear, and these groovesare semicircnlar, or nearly so, to correspond to the beaded or upset endof the boiler. tube or tine. The swag-ing-rollers 9 start or give theinitial bend to the projecting end of the flue or tube 11, and thecalking-rollers givethe linishing turn tothe bead l2 and are formed witha cutting edge 13 to remove any surplus metal and to insure a iirinengagement between the bead 12 and the portion of the boiler-head 14bordering upon the opening in which the fine or tube 11 is fitted.

A retainer 15 is rotatably mounted upon the outer end `of theshank 1,and its inner end is flanged, as Shown at 16, and is provided With aseries of pockets or openings 17,

in which the several rollers are fitted and so asto `retain the rollersin place in theirpockets.

l he end of the Stem 1 opposite the shoulder 2 is threaded, as shown at20, and `is adapted IOO , a screw-thread connection with the said rod bymeans of Ithe coupling 21. By turning the stockthe tool is advanced,thereby forcing and crilwding the rollers 9 and lO against theprojecting end of the tube, said stock being turned in' any convenientWay, preferably by tting a rod in one of a series of openings 23, formedat intervals in the shoulder 2. After the rollers have' been'broughtinto forcible engagement with the projecting end of the iue the head 3is rotated, thereby turning the vpro'j'ecting endA of the flue. Afterthe head 3 has been rotated once or any required number of timesthestock is again turned to advance the rollers to the work, therebygrad ually edecting the beading, it being remembered that. the head 3 isrot-ated between each successive advancement of thestock. The head isformed with a series of openings 24, which receive a rod or otherimplement, by means of which it is rotated, so as to edect ythe desiredend. After the end is completely beaded the tool is removedand fitted toanother fiue or tube andthe operation herein described repeated. v

` Having- 'thus described the invention, what is claimed as new isl. ina tool for beading boiler r'iues or tubes, the combination of a revolubie head,and sWaging and calking rollers alternately arranged anddisposed at different angles, whereby one set of rollers starts or givesthe initial bend and the other set completes the beading or upsetting,substantially as specified..

2. In a tool for beading boiler tubes or flues, the V`Y`:embination of arevoluble head, swaging-.-.ollers disposed at intervals around thevrevdluble head. to start or give the initial bend to boiler-fiue,andcalking-rollers arranged ii'il'erinediate of the swaging-rollers and ata diiierent angle thereto, and PlQvided with lcutting edges,substantially as and for the purpose set forth. 3. Inatool for beadingboiler tubes or iiues, Y the combination of a revoluble head providedWith oppositelyinelining` faces forming tracks, and rollers adapted totravel upon the said tracks, substantially as and for the purpose setforth. l A

4c. In a tool for beading boiler tubes or ues, the combination of arevoluble head having ppbsitely-inclining faces, each -formedwith a beadproviding a'track, and rollers alternately arranged and disposed totravel upon the said tracks substantially as and for the. purpose setforth.

5. In a tool for beading boiler tubes or flues, the combination of arevoluble head, rollers" adapted to travelupon the revoluble head, and aretainer having openings to receive the' rollers and hold them in place,substantially asset forth.

6. In atool for beading boiler tubes'or flues, the combination of arevoluble head, rollers obtaining a bearing against the revoluble head.,a retainer having openings foi-"receiving and securing the rollers inoperative position, and a band secured to the retainer for holding therollers in place, substantially as set forth.

7. The herein-described tool for beading boiler tubes or fines,Vconsisting of a stock h av-4 ing a shoulderand provided With-means tbpositively advance it to the work, a head revo-` lubly mounted11p-.initile stock and 'having opi positely-inclining faces providedwith/annular. tracks, antif-riction-bearings between the revoluble headand shoulder, sv'vagingand calking rollers haring peripheral grooveswhich receive the' annular tracks and which effect the beadingorupsetting of the flue-or tube, and a retainer formedwith a flange havfing pockets or openings to receive .the afore;l v

- said rollers, substantially in the man-ner and for the purpose setforth.

` In testimony that I claim the foregoing as my own I have heretoaffixed mysignature in the presence of two Witnesses.,

WILSON F. Murchison.
